Answer:
D. It’s only useful for monitoring organisms that are fixed in one place.
Explanation:
Point count method of population monitoring involves standing in a specific location and counting a population of animals, usually birds. The number of birds or the specie of bird within a circle of a specific radius is counted. The radius is usually made as big as possible in order to maximize information gathering. This type of population monitoring method can only be used for animals that have fixed location, for instance, birds living in a particular ecosystem.
Answer:
Proton motive force, compounds such as ATP.
Explanation:
Large amount of proton motive force(PMF),the usable enegy for the cell ,are produced during electron transport chain when high energy compound such as ATP pump hydrogen ions against the concentration gradient.
When the protons are transported against their concentration gradient at that time proton motive force is generated.
PMF generates energy for the synthesis of ATP by the phosphorylation of ADP with inorganic phosphate.
Answer: Meiosis is the necessary process for the inherited traits of an organism to be passed along by sexual reproduction to bring about variation.
Explanation: Meiosis occurs in reproductive cells. It halves the chromosome number of parents to produce same (constant) number of chromosomes in the offsprings.
Meiosis leads to genetic variation among offsprings through recombination, crossing over, independent assortment and reduction and fusion of gametes.
Most abnormalities that are heritable are as a result of improper division during meiosis.
